However, if you are using a 5 V supply voltage, then a 90 Î© resistor is needed. As you can see, the resistor value increases as the supply voltage increases
The graph below shows the power consumed per pixel (white, RGB all on) at different brightness levels. Rather than just assuming the default 60mA per pixel, we can more accurately match our LEDs and power supply. For example if we have a 5 amp power supply and want to hookup 150 LEDs, that gives us a power budget of 33.3mA per pixel (5000mA / 150) Make sure to have a large enough power supply by giving yourself a 20% cushion over the total wattage you calculate from your LEDs. This can easily be done by multiplying your total wattage by 1.2 and then finding a power supply rated for that wattage. Say for example we have 4 runs of LED strips that run at about 12 watts each Length of LED strip (measured in feet) x watts per foot x 1.2 = minimum rated LED power supply required to power your strip light Luckily for you, we have a power supply calculator on the product pages of all of our LED strip lights Supply Voltage VOLTS Voltage Drop Across LED (Forward V) VOLTS Maximum LED Current MILLIAMPS Calculated Limiting Resistor OHMS Nearest higher rated 10% resistor Calculated Resistor Wattage WATTS Safe pick is a resistor with power rating of WATT

To calculate the current limiting resistor, you first need to look in the datasheet (always RTFM first!) for the LED's recommended forward voltage and forward current specifications. In this example, they are 3.1V and 30mA respectively To calculate an LED's power use, simply multiply the LED's voltage (in volts) by the LED's current (in amperes). The result, measured in watts, is the amount of power your LEDs use. For example, if your LED has a voltage of 3.6 and a current of 20 milliamperes, it will use 72 milliwatts of power DC watts to amps calculation. The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):. I (A) = P (W) / V (V). AC single phase watts to amps calculation. The phase current I in amps (A) is equal to the power P in watts (W), divided by the power factor PF times the RMS voltage V in volts (V):. I (A) = P (W) / (PF Ã— V (V)). The power factor of.
